Sterling silver necklace with heart pendant

I lost my sterling silver necklace yesterday around 3pm near the fountain outside City Creek Center on Main Street in Salt Lake City. The chain is about 18 inches and has a small heart pendant roughly 1 cm across, with a tiny compass charm dangling near the clasp. The back of the pendant is engraved with the initials 'PP.' The chain is a bit tarnished from daily wear, and the pendant glints when the sun hits it just right. It’s really sentimental to me because it was a gift from my grandmother and I wear it almost every day. If anyone happened to see it or picked it up, I’d be incredibly grateful to get it back.
